To all whom it may concern.-

1 Be it known that I, PERCY TARBUTT, a citizen of England, residing at 23 St. Swithins Lane, in the city of London, England, have invented a new and Improved Ejector Oil- Vapor Lamp, (for which I have obtained patents in Great Britain, dated January 14, 1888, No. 624; in France, dated October 18, 1888,

No. 193,615; in Belgium, dated October 26,

1888, No. 83,743; in Cape of Good Hope, dated .December 14, 1888, Folio 492; in New South Wales, dated December 27, 1888, No. 1,140; in South Australia, dated December 27, 1888, No. 1,203; in Italy, dated January 15, 1889, Vol. XLVIII, 156; in India, dated January 16/23, 1889, No. 116/138; in Spain, dated February 12, 1889, No. 8,952; in Austria-Hungary, dated May 4, 1889, No. 44,088 65,484, and in Queensland January 16 and-April 25, 1889, No. 663,) of which the following is a specification.

This'invention relates to a lamp suited for producing a large and brilliant flame available in exposed situations by' the ejector action of an air-jet on the vapor or gases generated from oil by heat in the lamp itself.

The accompanying drawing is a vertical section of the lamp.

Its lower part is a vessel divided by a horizontal partition A into two compartments. The lower compartment B is supplied with air under pressure by a pipe from any suitable air-compressing apparatus. The upper,

compartment D is supplied with oil from a cistern E, which is provided with a float cock or valve governing a pipe F, leading from an oil-reservoir, which may be at a distance, so as to be removed from proximity to the flame of the lamp. By means of the float cook or valve the level of the oil in the compartment D is maintained approximately uniform.

In the center of the partition A is a nozzle or jet-tube G, which projects a little above the oil in D, and which has its lower mouth governed by a screw-plug H, so that a greater or less current of compressed air can be made to issue as a jet from G.

A conical cover K, open at the top, has through it near its lower edge a number of small holes k, for admittinga small supply of go ing kindled, and receiving a little supply of 5 air through the holes laburns with a lambent I flame over the surface of the oil, generating v vapor or gases therefrom. The jet of air through the nozzle G causes the combustible gaseous fluid mixed with airto rush through the mouth of the cover K, and, additional air meeting it there, the Whole, when kindled, produces a high and brilliant flame. As the cover K soon becomes heated, the oil vapor and gases are generated in considerable quantity and are heated as they ascend in K, causing the lamp shortly to attain its maximum illuminating-power.

Having thus described the nature of this invention and the best means I know of carrying the same into practical effect, I claim- 1. A vapor-burning lamp consisting of a vessel divided by a horizontal partition into an upper oil-containing compartment adapted to receive oil from a cistern and a lower compressed-air compartment having a pipe for connecting with a source of compressed air,

a conical cover resting on the vessel, having 7 an open top and provided at itsbase with a series of perforations arrangedabove the said vessel, an air-jet tube supported by said horizontal partition rising therefrom and communicating through the same with the compressed air in the lower compartment to force the combustible gaseous fluid upward through 8 5;

the open top of the conical cover, and a plug or valve which governs the quantity of compressed air passing from the compressed-air compartment into the jet-tube, substantially as described. o

2. A vapor-burning lamp consisting of a vessel divided by a horizontal partition into two compartments, the upper one being an oil-compartment and the lower one being an air-compartment and having a pipe to connect it with a source of compressed air, a conical cover having a perforated base and mounted on the vessel, a conical hood located over the cover, separated therefrom by a surrounding space and open at its base to V In testimony whereof I have signed my [5 name to this specification, in the presence of two subscribing witnesses, this 1-lth day of November, A. D. 1888.

PERCY TARBUTT.
